Robbie initially denied having the affair with Leah that ended her second marriage. However, now Robbie tells InTouch Weekly what really happened. He and Leah had allegedly been surreptitiously speaking on the phone. He admits, “I asked her if she wanted to come over and talk [in October]. Leah didn’t hesitate. She came right over.”

Robbie reveals (via RadarOnline), “One thing led to another and we had sex. We wore protection. That was the one and only time.”

He explains why it happened, “Whenever things are going bad in our lives, we reach out to each other, and this is what happens.” Robbie separated from Monica Haas, mother to their seven-month-old Averie, then got back together after the Leah hookup.

Robbie says that Leah and pipeline engineer Jeremy, who often travels for work for days at a time, had problems for a while. “Leah felt really alone because Jeremy’s gone a lot for work.” Robbie adds, “She said Jeremy doesn’t care about her or their family when he’s gone. All he wants to do is talk about sex.”

“We’ll always have a connection, but I’m tired of the drama,” he continued. “I’m finally happy with where I’m at in my life. I don’t want anything to do with her anymore.”
